Making a seven layered density column is a fun and easy science experiment. Have
you ever noticed two substances that don't mix together - like oil and water. This is
explained by the different densities of the substances. Both substances have the same
amount of volume, however one has more mass or weight than the other. To
demonstrate this we can make a seven layer density column.
Materials Seven Layer Density Column
- Honey
- Water
- Karo Syrup
- Liquid Dish Soap
- Rubbing Alcohol
- Vegetable Oil
- Lamp Oil
- Turkey Baster
- Bath Tints or Food Coloring
- Measuring Cup
Process To Make A Seven Layer Density Column
1) Get your measuring cup out and pour 7 ounces of each liquid into a separate cup.
2) Use food coloring to make each liquid more visible.
3) Add the honey first to the bottom of your cylinder.
4) Next use the Turkey baster to add the following liquids in this order: Karo Syrup,
Liquid Dish Soap, Water, Vegetable Oil, Rubbing Alcohol, Lamp Oil.
5) Be careful when making the layers. Gently, fill the baster with liquid and disperse it
on top of previous liquid without splashing it on the side of your cylinder or glass.
Gently disperse it right in the middle for best effect.
The Science Behind The Seven Layer Density Column
The greater the weight a substance has, the greater it's density is. All substances don't
weigh the same. When we layer liquids that have lower density on top of liquids with
higher density, the less dense ones float on top. If you were take a scale and weigh
each of the substances used in the seven layer density column you would find each
weighs differently (make sure you measure out equal amounts before putting on a
scale (7 ounces). Now go grab some friends and make a seven layer density column!
